Application ld Oetober 16, 1915. Serial No. 56,263.

To all whom it may concern.' a i `Be itlnownthat we, PETER WILVERT and NICK VAGNER, citizens of the United States, residing at Tintah, in the countyof Traverse and State of Minnesota, haveV invented new anduseful` Improvements in Track-Sig-- j upon theroad maybe given visual indication as to whether a train is approaching a crossing.

It has for its primary object the pro-` vision-of a device of this character whereby the signal proper, can beactuated from a distance by a train. i i p .Another obj ect of the invention is the provision of mechanism set into operation by wheels of the train forthrowing the signals to dangerposition and other mechanism arranged to come into contact with the wheels of the train for' `returning f the `signal `t'o safety position after the train .has passed the crossing.- M y A further object of the invention is to provide rotary means coperatingrwith the trip mechanism whereby the Signal `may be thrown to a danger position and subsequently` thrown to a Vclear position without the train passing completely over the cross#4 still `further object` of the invention is the provisionof astructure wherein locking means is providedrforl holding the trip in a depressed positionV when once depressed so that it will not be continually struck bythe successive wheels of thertrain. f

The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accom`` panying drawings, inl which Figure l is a side elevation of our invention, the parts being shown in normal position. Fig. 2 isa similar view showing the parts in an operative position. Fig. 3 is a top plan view. Fig. 4 is a side elevation of a portion of the track mechanism. Fig. 5 is a longitudinal sectional .v-iew of the track mechanism illustrated in Fig. 4. Fig. 6 is a detailed view of the trip. Fig. 7 is a perspective view of the trip. Fig. S is a perspective view of the locking lever. Fig. 9 is a vertical section through the standard.

place against the tension ofV the Fig. l() is a horizontal section through the standard and-casing.

Referring to the drawings,` the numerals l andZdesignate plates bolted to the rails at points spaced an equal distance from the signal standard 3. .As the construction secured to each plate is identical, we will limit ourde'scription to the mechanism of one plate, such as the plate 1. y

Pivotallymounted upon the plate l` at a point intermediate its lengthis a trip 4 hav-` ing an eye bolt 5 secured to its' lower eX- tremity anda shoulder G formed adjacent its upper extremity. At a point between its pivot and the upper end, the trip is provided with a second bolt? for a purpose to be described. p

Swingingly mounted upon the plate in close proximity to the trip is a locking lever 8 provided with a bill 9 and an upper cam surface 10. rlhe trip and lever are so arranged with relation i to each other that when the trip moves toward a horizontal position, the side of the trip will engage the cam surface of the lever and force the latter in a `direction to allow the bill 9 to engage the shoulder 6. For insuringthis operation, we have secured to thelever 8 a spring 11 and also secured to the trip 4 is a springlQ.

The standard 3 is provided with a cylin` drical extension 13 rotatably mounted inthe block 14 embedded in the road bed. Adjacent the cylindrical extension 18, the stand ard is squareas indicated atl and has secured to one corner thereof an eye bolt 16. rfwire cablel makes connection between the eye bolts 5 and 16 so that uponmovement of the trip toward the locking lever, a pull will be exerted upon the wire cable for moving the standard ina direction .to display a danger signal, this action taking coil spring" 18.

Referring to Figs. l and 2 of the d1'aw ings, it will be seen that the trip of the plate l has connection with the locking lever of the plate 2 by means of the wire cable 19, while the locking lever of the plate l has connection with the trip of plate 2 by means of the wire cable 20. From this arrange ment, it will be seen that when either of the trips is moved in a direction away from its associate locking lever, the other locking lever is retracted from its associate trip.

The signaling means comprises a lamp 9.1 arranged in a through passage 22 formed in the upper portion of the standards and a signal blade 23. An extension 25 is formed on the blade 23 and projects through the top plate 26 of a cylindrical casing 27 so as to be rigidly connected to the standard 3, the casing being provided with a pair of diametrically arranged openings 28 through which the lamp 21 may be viewed when the standard is rotated for throwing the signal blade into danger position. The casing 27 is held against rotary movement by means of the braces 29 secured to the block 1A. As the train approaches the crossing from the left, the trip lever of the plate 1 is struck by the front wheels of the locomotive and is depressed and held in a depressed position by the associate locking lever. Simultaneously with the moving of the trip to a horizontal position, the standard is given a rotary motlon by means of the cable, for positioning the lamp within the opening of the standard and turning the signal blade in a direction parallel with the track. As the train proceeds on and passes the crossing, the front wheels of the locomotive strike the trip or plate 2 and by means of the wire cable, the locking lever of the plate 1 is retracted for allowing the trip to assume a vertical position which action allows the standard to rotate to a clear position.

The before mentioned mechanism Works accurately in conjunction with a. through train, but in case a train moves back and forth within the space between the plates 1 and 2, we provide the mechanism A arranged adjacent the plate 1 and the identical mechanism B arranged adjacent the plate 2.

` This mechanism comprises a shaft 30 rotatably mounted in a tube 31 rigidly secured to depending brackets 32 secured to the rail. One end of the shaft 30 has secured thereto an arm that has connection by means of the chain 33 with an end of the adjacent locking lever 8. The remaining extremity of the shaft is provided with an arm 34, normally engaging a second linger 35 that is secured to the arm 36 pivotally connected to one end of the track rail. For normally holding the arm 36 in a vertical position, we provide the springs 37 and 38. From this arrangement, it will be seen that when the arm moves in one direction, the shaft is rotated for retracting the locking lever, but when rotated in the opposite direction it has no action upon the shaft. lVhen the train strikes the trip 4L and sets the signal, the signal will stay in this position while the train is intermediate the plates 1 and 2. Upon the train backing toward the trip that has previously been thrown to an operative position and caught by the bill 9, the arm 36 will be depressed for actuating the shaft, which in turn retracts the locking lever 8 for allow-1 ing the signalto return to clear position.

For inclosing the mechanism arranged along the track, we provide the casing 39.

Having described the invention, what is claimed is:

1. A railway signal comprising a rotatable standard, signaling means carried thereby, a pair of pivoted trips spaced an equal distance from the opposite sides of said standard and operatively connected thereto, locking levers coperating with said trips each of which having a connection with a remote trip, and rotatable means cooperating with each locking lever whereby a locking lever may be thrown to an inoperative position from an adjacent point.

2. A railway signal comprising a rotatable standard, signaling means carried thereby, a pair of pivoted trips spaced an equal distance from the opposite sides of said standard` and operatively connected thereto, a shoulder formed on each trip, locking levers each mounted :for pivotal swinging movement and adapted when in one position to engage the shoulder on `the associated trip, and independent rotatable means for each lever whereby the lever may be disconnected from a trip.

In testimony whereof we affix our signatures in presence of two witnesses.
